INTRODUCTION

SAFETY

A fireguard conforming to BS 8423: 2002 should be used in the presence of children and old/or infirm people. If the appliance is used with the fire door open, a spark guard conforming to BS 3248 should be fitted.

Do not use aerosol sprays or any other flame near the appliance under fire. Do not fit an extractor fan in the same room as the appliance. Fire cement is caustic, hand and eye protection should always be worn, prolonged contact with the skin should be avoided. Aarrow Fires Ltd will not be responsible for any consequential or incidental loss or injury however caused.

Before continuing any further with the installation of this appliance please read the following guide to manual handling.

• Always obtain assistance when lifting the appliance.

• When lifting always keep your back straight. Bend your legs not your back.

• Avoid twisting at the waist. It is better to reposition your feet.

• Avoid upper body/top heavy bending. Do not lean forwards or sideways when handling the fire.

• Always grip with the palms of your hands. Do not use fingertips for support.

• Always keep the stove as close to the body as possible. This will minimise the cantilever action.

• Use gloves to provide additional grip.

THE PRINCIPLE OF THE FIRE

Your Aarrow Fire is built to the highest standard of craftsmanship using the best materials and the most modern equipment available. It is a highly efficient and sophisticated piece of machinery and when properly installed and operated it should provide a lifetime of heating satisfaction.

Safety is the most important consideration when installing your fire. If not properly installed and operated a house fire may result. Installation must comply with the Building Regulations and conform to all relevant fire safety standards.

Aarrow Fires produce a variety of appliances ranging from units, which are traditional in style to stoves which are modern in appearance, all bristling with "High Tech" features.

Model types include simple room heaters, convectors, integral boiler models and inset units. Your Aarrow Fire is constructed from either single or twin wall steel strengthened where necessary. Cast iron is used where appropriate for decorative features.

All fire doors are fitted with special high temperature ceramic glass panels through which the fire can be viewed.

Multifuel stoves are fitted with a cast iron grate to give full multifuel facility and positive de-ashing.

All models except integral boiler models are lined with firebricks or heat reflective panels which ensure complete combustion and provide a good heat store to even out fluctuations in burning.

An internal throat plate produces turbulence to encourage secondary combustion and directs the flue gas around the whole upper firebox before allowing it to escape up the chimney.

On multifuel appliances the primary air for burning enters the ash pit chamber beneath the grate, controlled by the air inlet mechanism.

Aarrow Fires are also fitted with an "air wash" so called because it provides a curtain of high speed preheated air behind the glass to help keep it clean and to provide secondary air/over draught.

The provision of two inlets on all multifuel stoves gives a wide range of primary air/secondary air, under draught/over draught combinations. The optimum settings will only be established by experience in firing the appliance, and will depend on type of fuel, the position of the appliance in the house, condition of chimney etc.

MULTIFUEL GRATE

The Aarrow Multifuel grate comprises of a series of reciprocating cast iron bars seated on a pivoted "comb". These should come fitted in your stove, if not please refer to page 16 for fitting and operation and also operating instructions on fuels for correct settings of the grate.

AIR INLET CONTROLS

Stratford multifuel stoves have three air inlets:

•The air wash system (so called because its pre-heated high speed air washes across the inner face of the door glass, keeping it clear), which provides over draught, and

•The primary air inlet providing under draught to the base of the fire chamber through the gap between the body and the ash pit door.

•Most importantly on the Stratford Boiler stoves is the thermostatic control system.

Please note partial opening of the ash door will over-ride and negate the thermostatic control.

THERMOSTATIC CONTROL

Stratford Tf Integral Boilers have a

thermostatically controlled side air inlet, beneath an access plate. The damper plate at the rear/side of the appliance regulates the amount of under draught entering, depending on the setting of the thermostat control knob (located at the bottom front on the left hand side of the unit) and the temperature of the water transmitted through the sensor phial in the water

jacket. Stratford Tf and Ti with the ash door fully shut,

the settings range from 0 (fully anti-clockwise) a shut-off setting at which the damper will shut off the underdraught completely, causing the fire to die down and in time go out, to 8 (fully clockwise) the highest setting at which the appliance will burn fiercely and produce very high outputs.

For more information on the Ti inset model please see page 20.

Note: The area around the thermostat, both inside at the back of the firebox and externally, must be cleared of ash and other debris regularly. (See page 13). For setting instructions refer to "Checking Thermostat" on page 19 .

AARROW AIR WASH SYSTEM

The air wash has an internal sliding plate with slots, housed in a cover plate, and is located above the fire door. Sliding the control shaft to the right as far as it will go achieves the fully open position. Sliding it to the left will shut off the air inlet slots. The operating tool should be used to tap the control shaft to the desired setting.

Fig. 1 Fully Closed Fig. 2 Fully Open

Note: Opening or part opening of the ash door is controlled by the "interlock" device located in the front of the unit (refer to INTERLOCK section on page 9). Even when all the slots are completely shut a "bleed" of secondary air will be maintained ensuring that inflammable gases are burnt off.

DISASSEMBLE AIR WASH

The Stratford air wash may be disassembled for cleaning or adjustment. To achieve this, the following procedure should be followed:

This should only be carried out when the fire is cold and unlit.

•Support Air wash cover with one hand

•Move cover up by smartly tapping the bottom with a hammer. (Fig. 3)

•Remove assembly from appliance.

•Clean and/or adjust.

•Refit using reverse procedure.

OPERATING INSTRUCTIONS

INTERLOCK SYSTEM

Stratford Tf and Ti Multifuel Boiler Stoves are fitted with an "interlock" system. A situation where the fire door is closed and the ash door is open may lead to serious overfiring which could damage the appliance. Correct use of the doors and interlock system will ensure that this does not happen.

Operation is as follows: A pivoted lug prevents closure of the fire door, unless the ash door has been shut first. When the fire door is shut the ash door knob can be turned anti-clockwise by up to 95 degrees creating a variable gap between the top of the ash door and the body, through which primary combustion air can enter the appliance.

Note: In order to turn the ash door knob sufficiently for the catch to release and permit the ash door to be opened fully THE FIRE DOOR MUST BE OPENED FIRST.

MULTI PURPOSE OPERATING TOOL

Your Aarrow fire comes with a multi-purpose operating tool which is used to open the ashpit door, riddling, setting the multifuel grate position and for emptying the ash pan. (see fig.4)

Fig. 4

RIDDLING

Use the operating tool for setting the grate in the coal burning position or the wood burning position. This means that effective de-ashing takes place, and also allows the grate to be set in the coal burning or wood burning position, as indicated on the right hand side of the appliance.

DOOR TRIM

Stratford fire doors are fitted with a brushed steel finish trim as standard. This clips on to the small lugs at the top and bottom of the aperture in the cast iron fire door, as a "spring fit". When fitted, the trim locks the glass retaining clips in position. (Fig 5)

The fire door should be removed so that the above operations can be carried out on a workbench or similar. Remove the door by GENTLY tapping the door upwards; this will lift off of its hinges.

Trim Fit Fig 5

FIRE DOOR GLASS

If necessary the glass can be removed as follows

Step 1 Remove the brushed steel finish trim by pressing on the curved edge at the top until the trim can be disengaged from the lugs.

Step 2 Slide the two glass retainer clips on one side only, inwards, towards the centre of the door as far as they will go.

Step 3 Pull this side of the glass away from the door casting, easing the tags on the glass retaining clips past the edge of the aperture in the door casting.

OPERATING INSTRUCTIONS

Step 4 Remove the glass completely. Store glassretaining clips and white gasket (if sound) safely for re-use.

Step 5 Follow this procedure in reverse to fit replacement door glass or gasket.

DOOR ADJUSTMENT

The catch can be adjusted by sharply tapping the catch on the inside of the door.

Once the appliance has been under fire for a period of time the fire door may appear to have moved out of alignment with relation to the door aperture or catch on the door interlock mechanism. This is quite normal and due to the settling of the casing.

The fire door can be re-aligned by the user as follows:

•When the appliance is cold, open the fire door so that it is at a right angle to the front face of the fire.

•Lift the fire door up off the hinges.

•Gently tap the two hinge pins in a direction to compensate for the misalignment.(fig 7)

Fig. 7

•Refit the door and check to ensure it now sits square to the body; if not repeat above steps.

Raising the door as follows:

•When the appliance is cold, open the fire door so that it is at a right angle to the front.

•Lift the fire door up off the hinges.

•Drop one washer on the top and bottom hinge pin.

•Refit the door and check to ensure door is free of the interlock. If not remove and repeat fitting second washer.

FUEL RETAINER BARS

Fuel retainer bars are supplied with the fires. For wood burning, 1 fuel retainer bar is used, affording a better view of the fire. Slide and lift the bar until it is clear of the guides at each side, and remove through the fire door opening. The bars are symmetrical and of even lengths making incorrect fitting impossible. Note: This operation should only be carried out when the appliance is unlit and cold.

OPERATING INSTRUCTIONS

FUEL TYPES

Wood- Any type of wood is suitable provided it is

well seasoned and has a moisture content below 20%. This usually implies that the timber has been suitably stored to allow moisture to evaporate for at least nine months in the case of soft woods, and at least eighteen months in the case of hard wood. We recommend that for general burning, wood should be split into logs of no more than 130mm (5") diameter. Larger logs can be used for overnight burning.

WARNING wet wood must not be used as this will greatly contribute to the creation of tar and creosote which may, in extreme cases, run down the chimney in liquid form. This will seriously damage both the chimney and the appliance, and increase the risk of chimney fire.

Note: If you have sticky tar inside the appliance or chimney your wood is 'Green' or too wet.
